The experimental North American Sabreliner 50 plane has been owned by US company Rockwell Collins since 1976 and has led to innovations that are used in commercial and military avionics today. Only one of its kind was ever built.

The plane will be donated to the McMinnville museum in the US where people can gawk at the "eyesore". It's even been harshly reported as the "world's ugliest aeroplane".

We actually think it looks quite interesting.

The plane will be donated to the Evergreen Aviation & Space Museum at McMinnville, Oregon, US.

It was flown for 8000 hours, making over 5000 landings.

"We are very thankful to Rockwell Collins for retiring the aircraft to the museum and giving us the opportunity to educate visitors with the aircraft," Stewart Bailey, Evergreen's curator, told Fox12. "We understand how influential this aeroplane was for the aviation industry."

The North American Sabreliner planes are medium-sized business jets developed by North American Saberliner. Some were modified and sold to the military, others were developed into commercial jets.
